Pro tip: that $30 "smart" plant watering app nearly killed my whole windowsill
I set up the app on a Saturday in April, paired the little sensor with my phone, and let it tell me when to water my six plants. Three weeks in, the push alerts kept firing at 2am and the sensor read every pot as dry, even the one I had just soaked. I lost a fern and two succulents before I yanked the sensor and went back to sticking my finger in the dirt. The app wanted $7 a month for "advanced care plans" after the free trial, which is when I finally got it. Has anyone found a dumb timer that just works instead of trying to be my plant doctor?
